not be detected correctly and the system
may not operate properly. (The alarm may
go off accidentally, or the door lock pre-
vention function may not operate.)
●Do not leave the electronic key inside the
trunk.
The key confinement prevention function
may not operate, depending on the loca-
tion of the key (close to a spare tire [if
equipped], the inside edge of the trunk),
conditions (inside a metal bag, close to
metallic objects) and the radio waves in
the surrounding area. ( P.93)

sult the manufacturer of the device for
information about its operation under
the influence of radio waves.
Radio waves could have unexpected
effects on the operation of such medi-
cal devices.

WARNING
■When adjusting the seat position
●Take care when ad justing the seat
position to ensure that other passen-
gers are not injured by the moving
seat.
●Do not put your hands under the seat
or near the moving parts to avoid
injury.
Fingers or hands may become jammed in
the seat mechanism.
●Make sure to leave enough space
around the feet so they do not get
stuck.
■Seat adjustment
To reduce the risk of sliding under the lap
belt during a collision, do not recline the
seat more than necessary.
If the seat is too reclined, the lap belt may
slide past the hips and apply restraint
forces directly to the abdomen, or your
neck may contact the shoulder belt,
increasing the risk of death or serious
injury in the event of an accident.
Adjustments should not be made while
driving as the seat may unexpectedly
move and cause the driver to lose control
of the vehicle.
